Adaptive Control Method for Massive and Intensive Traffic in Communication-Broadcasting Integrated Services

This paper proposes an adaptive control method of delayed transmission for massive and intensive telecommunication traffic expected in communication-broadcasting integrated services. It furthermore presents quantitative evaluation of the proposed method through computer simulations and experiments using a test bed. Communication-broadcasting integrated services, which have been started by the terrestrial digital broadcasting, give rise to the massive and intensive traffic induced by a TV program. In years to come, when these services are widely spread and used, the magnitude of the massive and intensive traffic will increase significantly enough to cause severe congestion in communication networks. The proposed method adaptively delays data transmissions from viewers depending on the congestion state, so that the severe congestion can be avoided effectively. The quantitative evaluation demonstrates the effectiveness of the proposed method
